Lightbulbs. Simple, cheap, and easy to replace, right? Not anymore! Philips is dragging the humble bulb into the future with its "Hue" technology -- wirelessly controlled light orbs that give you complete control over the lighting in your house.
The Hue bulbs look like ordinary lightbulbs, and screw into light sockets as normal. Inside each bulb, however, is a wireless transmitter that communicates with a hub you plug into the back of your router.
Once connected, you can use a Web site or download an app (the iOS version is out now -- there's no sight of an Android version, though Gizmodo reports it's coming in December), then use the wonderful power of the Internet to fiddle with the lights in your home.
The special bulbs can spit out any hue in the spectrum, so the first thing you'll likely do is light your home in a terrifying riot of colors, then get all your friends around and meet them at the door screaming, "Welcome to the rainbow house!" in your underpants. Probably.
